Ford C-Max PCM causing vehicle to slow and shut down, potential transfer shaft assembly bearing failure on Ford C-Max

Some Ford C-Max owners report experiencing issues related to a malfunctioning Powertrain Control Module (PCM), which can lead to poor powertrain performance, unexpected slowdowns, or even complete shutdowns of the vehicle. These owners also note that a failing PCM may cause inadequate fuel delivery to the engine, resulting in more frequent refueling. Additionally, some owners report problems with the transfer shaft assembly bearing, where a failed bearing retainer can lead to bearing damage and gear teeth wear, potentially causing significant mechanical issues. This failure may also contribute to the vehicle slowing down or shutting down unexpectedly. It is recommended that owners experiencing these symptoms have their PCM and transfer shaft assembly inspected by a qualified mechanic for proper diagnosis and resolution.
